I agree completely, but what we want isn’t what the manufacturers want. The aftermarket industry gives them a headache. I’m not saying they want it to disappear, but they want to make it harder and harder for people to modify the drivetrain and then try and pull the wool over their eyes.
I agree that in a perfect world, everyone would work together and the b.s. would stop. But you and I both know, that ain’t gonna happen.
And your analogy isn’t correct, because I never said the manufacturers’ threatened to stop making cars. A proper analogy would be where Microsoft would try to make it harder and harder to pirate their software (via way of improved disc encryption, system registration, whatever), which they are in fact always doing (them and every other software maker).
